Embodiment 1

[0020] The anti-floating anchor rod waterproof construction method of the present invention comprises the following construction steps:

[0021] A. Clean the surface of the anti-floating anchor rod 1, put it vertically into the underground soil layer 2, and pour a concrete cushion 4 on the underground soil layer 2;

[0022] B. Pour cement paste 3 around the anti-floating anchor rod 1. The pouring height of cement paste 3 is the sum of the height of underground soil layer 2 and concrete cushion 4; Grout, do not shake anti-floating anchor rod 1 within 24 hours after grouting;

[0023] C. Clean the upper surface of the cement slurry 3 and the concrete cushion 4 within a radius of 250mm with the anti-floating anchor 1 as the center point, and paint the cement-based crystalline waterproof coating 5 three times, and the key painting part is the anti-floating anchor 1 and the junction of the concrete cushion 4;

[0024] D. After the cement-based crystalline waterproof coating 5 is ...

Embodiment 2

[0032] The anti-floating anchor rod waterproof construction method of the present invention comprises the following construction steps:

[0034] B. Pour cement paste 3 around the anti-floating anchor rod 1. The pouring height of cement paste 3 is the sum of the height of underground soil layer 2 and concrete cushion 4; Grout, do not shake anti-floating anchor rod 1 within 24 hours after grouting;

[0035] C. Clean the upper surface of the cement slurry 3 and the concrete cushion 4 within a radius of 300mm with the anti-floating anchor 1 as the center point, and paint the cement-based crystalline waterproof coating 5 three times, and the key painting part is the anti-floating anchor 1 and the junction of the concrete cushion 4;

[0036] D. After the cement-based crystalline waterproof coating 5 is ...

Embodiment 3

[0044] The anti-floating anchor rod waterproof construction method of the present invention comprises the following construction steps:

[0045] A. Clean the surface of the anti-floating anchor rod 1, put it vertically into the underground soil layer 2, and pour a concrete cushion 4 on the underground soil layer 2;

[0046] B. Pour cement paste 3 around the anti-floating anchor rod 1. The pouring height of cement paste 3 is the sum of the height of underground soil layer 2 and concrete cushion 4; Grout, do not shake anti-floating anchor rod 1 within 24 hours after grouting;

[0047] C. Clean the upper surface of the cement slurry 3 and the concrete cushion 4 within a radius of 350mm with the anti-floating anchor 1 as the center point, and paint the cement-based crystalline waterproof coating 5 three times, and the key painting part is the anti-floating anchor 1 and the junction of the concrete cushion 4;

[0048] D. After the cement-based crystalline waterproof coating 5 is ...

Abstract

The invention discloses a waterproof construction method for anti-floating anchor rods. The waterproof construction method for anti-floating anchor rods includes the following construction steps that A, a concrete cushion is poured; B, cement paste is poured around the anti-floating anchor rods; C, cement-based crystallization waterproof paint is brushed; D, a waterproof roll layer is laid; E, waterproof grease is poured, and a waterproof protection layer is poured. The waterproof construction method for anti-floating anchor rods has the advantages that gaps between the anchor rods and bed rock can be effectively sealed for avoiding water burst; the problem that because waterproof paint on the root portions of rebars of the anchor rods is not compact, water is prone to leakage is solved; a water stop steel plate can stop capillary water from rising along rod bodies to cause water seepage hazards, the water stop effect is good, and leakage resistance is improved.

Description

technical field [0001] The invention relates to a waterproof construction method for building construction, in particular to a waterproof construction method for anti-floating anchor rods. Background technique [0002] At present, in the underground structure of construction projects, the anti-floating anchor directly connects the bedrock and the bottom plate, and penetrates the waterproof layer of the base, so the possibility of water seepage increases greatly. At present, there is no anti-floating anchor node waterproof treatment in the current atlas waterproofing method, and the anti-floating anchor waterproof node treatment generally adopts the pile foundation waterproofing method of building waterproof structure; but the diameter of the pile foundation is usually larger than the anti-floating anchor diameter, compared to the pile foundation The horizontal operating surface is much smaller, and it is difficult to guarantee the waterproof effect when painting cement-based...
